CORPORATION OF DELAWARE STRIPIN G FIXTURE Application filed October a,1928. Serial No. 310,870.

This invention relates to the art of painting ornamental stripes. Insuch work as the painting of automobile bodies an ornamental stripe iscommonly employed for decorative effect, the stripe usually being donewith a hand brush which requires the exercise of a high degree of skillto secure uniform and properly positioned lines. Hand striping is slow,tedious, and extremely costly. V

It is now proposedto avoid hand striping as far as possible and to useinstead a striping tool or instrument which in the 7 hands of theordinary person without specialtraining maybe'manipulated to discharge asteady flow of striping material onto the work. To aid the workman inhis use of the tool a fixture or template is used to serve as a guide.In practice it has been found that the start and finish of a stripe laiddown by a tool guided along the templateis not as perfect as theremaining portion of-the strip and this is attributed to the theory thatthe flow ofstriping material at such times is not a steady one and thelines, therefore, are of, varying width and shade in accordance with thevarying amount of material delivered to the surface. As a remedy forthese conditions the present invention contemplates the use of a smallplate in association with the guiding edge of the template at both thestart and finish of thestripe, which will cover the work and shield itfrom the application of the striping material at such times when theflow is increasing or decreasing in value. Thus when theamount ofmaterial discharged is undergoing a'change'in value the deposit will beon the platerather than on the work itself and during such times as whenthe striping material is being laid down on the i work it will be in asteady flowso as to assureian evenlinefrom end to end. I

The invention will be more clearly understood upon reference to theaccompanying drawing illustrating a preferred but not necessarily theonly embodiment thereof and in whichdrawing Fig. 1 is a side elevationof a portion of an automobile body. with the template mounted ina-window opening.

Fig; 2 is a sectional view taken on line 22 of Fig; 1. Fig. 3 isa detailperspective View of the shield.

' In the drawing the reference character 1 indicates an automobile bodyhaving a window opening in which is positioned a fixture consisting of arectangular frame 2 formed of short lengths of wood and carrying aseries of'strips 3-8 preferably of sheet metal which provide the guidingedge for the tool. as it is moved around the-fixture to apply a stri ebordering the window opening. The fi Xture may be detachably heldin'position by any suitable means, as for example the latches 4 pivotedon the frame 2 and'which may be swung behind the sheet metal paneling ofthe body 1. The start and finish of the stripe will be at the lower endsof the vertical strips 3 and at these points there are secured to thestrips a plate 5 having a long leg Gprovided with openings 7 forattachment withthe strip 3 and: a short leg 8 bent inwardly so as to lieclosely adjacent to the surface of the work.

en a stripe is to be made, the striping tool is positionedv over thefixture along the guiding edge sothat the discharge portion of the toolis over the plate 5. As the flow of striping material commences, thedischarge will bereceived'upon the shorter leg 8 of oneof the plates3,'and by the time the end of the leg is reached the flow will havebecome steady so as to deposit upon the work a uniform stripe until theopposite end is reached, when the applying portion of the tool'passesover the shorter leg of the other plate 3 at which time the flow isagain cut off and the striping material discharged at a varying rate isdeposited upon the plate. From the above description it will be apparentthat the plate shields and protects the work from the application of thestriping material at all times when the value of the discharge isundergoing a change. Thus a line may be made which is uniform and ofeven width throughout.

I claim:

1. In a striping fixture adapted to guide a striping tool over the work,a protective shield offset with respect to the guiding por- ASSIGNOR TOGENERAL MOTOR-S COR- I tion of the fixture to overlie the work at a Ipredetermined point and over which the stripe applying portion of thetool may be passed prior to its passage over the WOIk.

'2. In a fixture for guiding a striping tool over the Work, a protectiveshield to overli'e and protect the Work from the stripe applying portionof the tool at the beginningor end of the striping operation. v
